There are three rules every starlet is supposed to follow. 1. Starve yourself into a size 00. 2. Date as many b-list boys as humanly possible. 3. When it doubt, don't wear pants.

Clearly, Kristen Stewart never got that memo. She has never fit into the typical Hollywood "It" girl mold and the Twilight star knows it. She tells the July issue of Vanity Fair:

"Look at a picture of me before I was 15. I am a boy. I wore my brother's clothes, dude! Not like I cared that much, but I remember being made fun of because I wasn't wearing Juicy jeans. I didn't even think about it. I wore my gym clothes."

But don't let her aloof exterior fool you. They fashion-challenged actress hated being the target of mean girls. "It's not like I didn't care that they made fun of me. It really bothered me. I remember this girl in sixth grade looked at me in gym and was like, 'Oh my God! That's disgusting -- you don't shave your legs!"

Not much has changed since high school. Even though she now has a closet full of cute frocks, landed a fragrance contract with Balanciaga and was named Best Dressed Woman of 2012 by Glamour UK, Stewart still gets flacks for her style and appearance. With her usually surly, slouchy demeanor on the red carpet, "I get some serious sh*t about it," she added. Not that she's losing any sleep:

"I'm not embarrassed about it. I'm proud of it. If I took perfect pictures all the time, the people standing in the room with me, or on the carpet, would think, 'What an actress! What a faker!' That thought embarrasses me so much that I look like sh-t in half my photos, and I don't give a f-ck. What matters to me is that the people in the room leave and say, 'She was cool. She had a good time. She was honest.' I don't care about the voracious, starving sh-t eaters who want to turn truth into sh-t."

Boyfriend Robert Pattinson certainly has no complaints about her looks. His take on his constantly criticized love: "No matter how many times she smiles, they'll put in the one picture where she's not smiling," he tells Vanity Fair. Well with Pattinson waiting at home to cuddle, Stewart clearly has plenty to smile about no matter what she's wearing.
